Frequently Asked Questions

Common questions about Hydroxylgel A2 & A4 (Dry Mix Co-thickeners) in construction applications

They are inorganic co-thickeners derived from chemically modified phyllosilicate. Unlike expensive organic thickeners, they provide thixotropy and sag resistance at lower cost while reducing chalking in dry-mix systems.

They are used in wall putty, skim coats, tile adhesive, standard mortars, plasters, and flowable mortar systems.

They are designed as partial replacements, significantly reducing the quantity of expensive organic thickeners needed while maintaining equivalent or better rheological performance.

The controlled hydrophobic-hydrophilic balance of Hydroxylgel A2 & A4 minimises binder migration to the surface, directly reducing chalking in cured dry-mix products.

Hydroxylgel A2 is the base grade for standard dry-mix applications while A4 W offers enhanced water absorption and hydrophilic performance, making it more suited for flowable and high-moisture absorption systems.
